METHOD FOR REMOVABLY SETTING GLASS PLATES.

Application filed June 14, 1915.

To all whom it may concern:

Be it known that l, EDMUND Mom-us, a citizen of the United States ofAmerica, residing at Grand Rapids, in the county of Kent and State of lllichigan, have invented certain new and useful Improvements in Methodsfor Remov'ably Setting Glass Plates; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the an to which it appertains tomake and use the same.

lrly invention relates to improvements for removably setting glassplates or panels in show cases, and more particularly to a means forsecurely, yet detachably setting and holding in place the glass platesor panels used in so called frame show cases and similar structures, andits object is to provide means whereby, when a glass plate or panel hasonce been fitted to and set in its proper position in the frame work ofa case it may, if desired, be repeatedly removed and replaced and itwill when so removed and replaced, always fit snugly into the place andposition where it was first fitted and set, doing away with alllooseness and the necessity of subsequent fitting and fixing intoposition.

While my improved methods is not limited to use in so called, knock downconstructions, it is particularly adapted to such construction, that is,in show cases which are erected at the manufactory, but which are thendisassembled and shipped in such disassembled or knock down condition,as will more fully appear by reference to the accompanying drawing, inwhich:

Figure 1, shows a transverse section of a corner post or other portionof the frame work of a show case which is recessed for and adapted toreceive an edge of the glass plates or panels of a show case, with twoof such glass plates or panels in constructional position, also showingsuitable clamp for holding the same in place, said figure alsoillustrating my improved method for providing a closely fitting seat orbed in the frames for the edgesof said glass plates; Fig. 2, is a planview of the spring edged strip which I employfor holding the glassplates or panels in place for the double form of post or frame shown inFig. 1; Fig. 3, shows a transverse sect1on of a post Specification ofLetters Patent.

or portion of the frame work of a show case, and the spring edged stripof the forms used where only one plate or panel of glass is to besecured; and Fig. 4, is a plan view of the spring edged strip which Iuse in connection with the form of st or frame work shown in Fig. 3.

Like numerals refer to like parts in all the figures.

1, represents the corner post or any part of the frame work of a showcase which is adapted to receive and hold the edge of the glass platesor panels; 2, are such glass plates or panels; 3, is a spring edgedmember held in operative position by the screws l, for holding the glassplates or panels in constructional position in the frame of the showcase.

In erecting a show case, utilizing my improved method therein, 1 firstset up the complete frame work and fit everything to its place. I thensupply two or more of the recessed angles of the frame work, which areintended to receive the edges of the glass plates or panels, with arequisite quantity of a plastic material 5; the edges of the glassplates or panels 2, which are to be beveled as at 2, are then pressedinto place as shown in Figs. 1 and 3, after which any surplus of thesaid plastic material which may be forced out beyond the edges of theframe work when the plates are embedded is removed, and the glass platesor panels are allowed to remain in said position until the said plasticmaterial has sufficiently hardened so that it will retain its form andposition. After said plastic material has once set so that it willretain its form and position, the glass plate or panel and the frame aremarked so that the said plate may be returned to the same place andposition in which it was first set, after which such plate may berepeatedly removed and replaced, as occasion may require, and such platewill always thereafter fit into its place as snugly and perfectly aswhen originally embedded into place in the plastic material.

It will be found of quite an advantage to dust or paint the edges of theglass plates or panels where they come in contact with the said plasticmater1al when they are first embedded therein, with talc or some similarsubstance, so that in. the first removal of the plate or panel theplastic material will not adhere to the same. The plastic lit) materialto be used may be any one of several well known substances, viz: putty,preferably prepared so that it will set and dry rapidly; plaster ofParis; modeling; compound; various waxes prepared with a hardener; etc.

I do not wish to be understood as limiting my improved method to the useof any particular form of plastic material, as there are a great numberof substances Well known, which may be employed with equal good resultsand advantage.

My invention consists essentially in beveling two or more of the edgesof the glass plates or panels, forcing the edges of such plates whichare so beveled into a bed of plastic material which has been previouslyplaced in the angle of the frame which is intended and adapted toreceive the edge of such plates or panels, permitting said plasticmaterial to set or dry so that the same will hold its formand positionwhen the glass plate or panel is removed, so that said plastic materialwill form a permanent beveled edged bed or seat to removably receive andhold the glass plate or panel in a snug and firm position. After theplastic material has once set or dried, the glass plates or panels maythen, as occasion may require, be easily, quickly and repeatedly removedor replaced, and yet the same will always fit closely and snugly in theoriginal position in which it was set.

The fitting and setting of glass plates or panels of show cases intoconstructional position, so as to prevent and avoid their being looseand shaky in their frames is a diflicult problem, but by utilizing mypresent invention, the fitting of such glass plates or panels may beeasily, effectively and cheaply accomplished, and when the plasticmaterial employed has once become fully set, the glass plates or panelsserve to brace and strengthen the frames, so that the whole structurebecomes more firm and rigid, thus very materially reducing the liabilityof breakage of the glass plates or panels as a required to be beveled,that is, any two of i the edges which form a right angle, and the saidplastic material is to be supplied in the angles of the frames toreceive such beveled edges, the other two edges of the plate or panelmay rest directly on the framework. Or again, three of the'edges may bebeveled and the fourth edge rest on the frame, or, all of the edges maybe beveled. The essentials of my invention being embodied in beveling asufficient number of the edges of the plate and supplying a plasticmaterial bed for such beveled edges, so that the plate or panel may befirmly held in its frame with all of its edges in contact with eitherthe frame or the plastic material bed, and yet such plate, by rea son oftwo or more of its edges being beveled,may be easily removed from itsframe and again replaced in its original position without subsequentfitting or fixing to snugly and firmly replace it in such position inwhich it was originally set.

I claim:

A method for detachably and tightly securing a plate or panel of glassin a frame, comprising; beveling two or more of the several edges of theglass plate, providing the angles of the recesses of the frame which areadapted to receive the beveled edges of said glass plate with a plasticmaterial which will harden, embedding the said beveled edges of saidglass plate into said plastic material, leaving said plate in saidposition until said plastic material has hardened, and providingdetachable means for holding the said glass plate in constructionalposition in its frame.

In testimony whereof I hereunto affix my signature to the foregoingspecifications and claim.

EDMUND MORRIS.
